rhis inyention relates `to certain new and useful'improvements in mining and lloziding in nchinee of the clans adapted to bleek-down p eviously undercut cool `and load it -into coiiveniently ,placed cnis oiriemovel from the mine.

T ie especial object of this. invention is to provide, in n meehineot theclnse desciihed, an improved arrangement of' conveying mechanism adapted to he positioned to .ieceive the coal as it is hiolien down and remove it rearwardly ofthe mzichine associated -with hieziling down devi/ee which are adjustable i'elntive to the seid convcyei's and to the materiel 'which is to he broken down,

The ymain fname A consists oi a. fhoiizontnlly extending` ,pan-like .structure l havingn cenlnnl :longitudin :illy extending1 rib member 2 ,Which divides the pan into `two lparallel tioughs.y ln these Atroughs nre .disposed 'the moving` pants of theeonvever B which Iletter consists ot' n chain'fcoiryingsuitahly spe-ced v nes oii'liglits e.

This isA neeeeszn'v, because `the meer Ypart of the mein frame eis inclined npwnrdiand ieaiivnid as shown in ig. 2.

The main 'ironie A. yhas e. plate-like extension i5 which underlies the vupwardly kinclinedportion of the fiume. n yolie which is mounted on the pleite oi' lhase 5 extends upvfeid overtlie inninpartoiithe frame 1 to Whioh yit isiigjidlli)7 attached. @n the upper end oi the yoke is formed n hearing for the veiticel shii 8, andthe lovvei pni't of tliisfshaft has a` hen-Enig; 9 eniiiied bythe frame' part l. l0 is e sprocket Wheel inst on the shalt 8 which dives the conveyer chain 3'the .shaft being' driven by lthe .motor lll. This motor 'is lmounted. ynoon e bracket 11 cei'iied yhy the inclined port of the main 'treme A9 theshnft Q of Enid motnd having a bevel pinion i3 which meshes with thehevel gen1: 14 on the shett S. The endless-conveyor ntits ki'Fiont endpasses Lover sprocket Wheel l5 whichie suitably mounted on `thefizune A.

rlfhe cafiiiag'e C coniists of e buse ,pn-rt- 16 which slidnlol'v mounted upon theiih of .the i ame (see and upstnndingg henringg ni'nis oi1 pedestnls l?. TS 'The motor 'frame l2 has n lfoi'wafd extendingsect-en 12a. The rear end ot the shaft section 12u is supported by a bearing bracket 11CL and is connected by a disencageable clutch device 12b to the motor shart 12. The front end of the shalt l2"l is disposed in the bearings of the pedestals 1T, 18. Disposed between the pedestals 1T and 18 and mounted upon the sha-tt 12 is a swinging yoke composed ol two radius arms 19"L and 19h. The krear arm 19a of this yoke is formed at its inner` end with a segmental worm wheel 20. 21 is a worm which is mounted in a bearing bracket 22 secured to the pedestal 17 of the carriage. This worin meshes with the segmental worm wheel 20 and can be turned by means olf the crank 23 to cause the yoke to swing about its axis, it being understood that the shaft 12a turns freely in the yoke.

ylhe auger l) is rotatably mounted in the free ends of the yoke arms 19a, 19h, and is driven by a large spur gear 24 which is slidably keyed on the shaft 12il and which meshes with a spur pinion 25 secured to the shaft of the auger ll. T he auger in its pretcrred form carries cutting tools 26, 26 at its iront end. lt will be seen that with the auger mounted in the manner shown and described7 it is possible to drive it from the motor in any one of a variety of positions in which it may be placed by swinging the yoke through something over one hundred and eighty degrees. The carriage C upon which the auger is mounted is, as it was stated, slidably mounted upon the main frame, and a screw 27 which is mounted in its rear end in a bearing 28 and which at its `forward end is threaded through the base of the carriage, serves to move the carriage backward and forward on the main frame, a hand crank 29 being provided to turn the screw.

The auger D is provided with means for breaking the coa-l down after the auger has been driven into the coal. A preferred form of the breaking mea-ns is shown in the drawing. A. series ot hydraulic plungers 30, 30 are mounted in cylindrical cavities 3l, 31 termed in the auger, the` cylinders and plungers being disposed transversely of the auger and in one axial plane thereof. The cylindrical cavities 81, 31 communicate with each other through passages 32, 32, and the rearmost cavity o1" the auger is in communication with the passage which leads to the rear end of the auger shaft where it issues axially?. 34 is a hand torce pump which is mounted upon a bracket of the carriage C. This `pump has its suction passage in communication with a reservoir 36 which contains a supply of water or other suitable liquid. The discharge pipe 37 of the pump is connected to a hose 38 which in turn is connected to the passage 83 of the auger. the hose beingprovided its discharge end with a nozzle 39 which extends through a suitable stalling box 40. 41 is a by-pass pipe leading from the discharge pipe 37 oi' the pump into the reservoir 36. rlhe oy-pass is controlled by a. hand actuated control valve 42.

lfihen the pump is actuated7 the by-pass 4l being closed, the liquid is forced through the hose 38 and passages 32, 32 into the cylinders 31 and causes the plungers 30 to be forced outward. ik spring 43 is mounted under the head of each of the plungers 30 and serves to retract the plunger when the liquid pressure is withdrawn, which is done by opening the valve 42 in the byhpass 41 so that the liquid can flow freely back into the reservoir 36.

It will be seen that after the auger has been driven forward into the coal, as shown in Figs. 1 and 27 the hydraulic pressure can be applied to the plungers mounted in the auger to break down the underlying coal uoon the endless conveyer which extends into the bottom.y kert, it being understood 'that said bottom kerif is previously cut by any or the well known undercutting devices. The coal thus broken down is carried rearward by the endless conveyer B, and in order that it may be discharged into cars without manual labo-r7 l provide the auxiliary eon veyer F.

The conveyer F comprises a main trame part 44 in the form o1 an elongated pan which is divided by a central longitudinal rib part 45 into two paralle troughs to re- (reive the moving parts of the conveyer which, as shown, comprises a chain 46 and flights 47. The conveyer frame 44 has its front and rear end parts horizontal with an intermediate inclined part. .lt is supported upon a truck 48, the rear end of the conveyer trame 44 being provided with a depending pivot pin 49 which extends loosely through an aperture inv the upper end oit a bracket 50 on the truck. The iframe 44 carries on its under side a wheel 51 which is designed to run upon an arcuate plate 52 on the truck platform. Thus mounted on the truck, the frame can be swung through a considerable range about the pivot 49.

ln operation the conveyer F has its receivin g end disposed beneath the rear end of the conveyer B, and preferably the conveyer F is driven from the motor E which drives the convcyer B. 58 is the driving' sprocket wheel on the conveyer lf, it being mounted on a short shaft 54 which is mounted in a suitable bearing 55 carried by the pan 44 of the conveyer. (See Fig. 6). -An idle sprocket wheel 56 for the conveyer cha-in 4G is mounted in a similar manner at the rear end of the conveyor F. The upper tace oiC the sprocket wheel 53 is termedl with clutch teeth 57 which are adapted to be engaged by the teeth of sliding` clutch 58 which is slidably connected upon the lower end of the sha-tt 8 and which can be raised and lowered CIK :memes by a vhand lever 59. llllhen the receiving end il? the conveyor F has been `moved under the discharge end oi' the conveyer B, the driving sprocket 53 of the former conveyor 'can be operatively connected to the shaft 8 .of the conveyer B by simply lovvering the clutch`58. ln this Way too the tivo conveyors are pivotally or flexibly connected to each other, and as the truck 48 is tree to m-ove on the tracli.y it will be seen that lthe conveyer l*1 will be automatically maintained in Working relation 'with the main Jiframe A of the Inaehine when the latter'is moved laterally along the face of the coal.

To effect the lateral movement of the machine along the face, I provide suitable power devices as follows:

@n the base part 5 ot the main treme er Vis mounteda stud shaft upon which is rotatablymounted a spur `gear 6l. This Ies-r ha on 'its upper side clutch teeth 52 which are at all ytimes in engagement with the Ateeth of a sliding clutch 68. 6a is a toothed clutch disc fast on the lower end oi the shatt oi" conveyer Rand by sliding the clutch G3 upward into engagement with the disc 6ft, the latter is connected -to the gear (il. 65 is a suitably mounted hand lever designed to shift the clutch 63. 66 is a WindingY drum arranged to turn about a vertical'axis, and G7 isa large spur `@gear connected. to said drum `and mounted in mesh with the gear (l. One end oit the cable G8 is secured to the Windingv drum' and thence entends tothe lei-t parallel to the tace, passes over pulleys G9 and 70 which are anchored in any suitable `manner by 'jacks or props 7l, 72, and thencepasses along the tace of the coal to the machine, being' made tast at 'l2-3 to the inf-in i 'aine It will be seen that Twhen the clutch is thrownto operative position, the Winding' druino `is turned causing; the cable-to be Wound up and the machine to be drawn laterally along the 'face of the coalVv Furthermore, the construction and arrangement'ol these devices is such 'that they are adapted to move the main frame laterally in parallelism so that it is maintained at the same angle to the coal tace. 74- isa pulley mounted on the base 5 at the left side ofthe machine, and is adapted to have 'the cable (353 passed over it and extended tornarci to a point adjacent the tace ot the coal and there made `rtast when it is desired to move the inachine endivise into the bottom hert.

lt is at times desirable to drivethe Winding' drum 66 when the conveyer F is not operative position. To maire this possil'ile,y l provide a short shaft section T5 Which is shoivnin 'Fig'. T. This shaft is designed to be inserted between the movable clutch members `58 and 63 and is t med atits ends with teeth to engage the teeth of said clutch members Byinserting the shaft section 75, the geiiifll. canbe'connected to the'shai't 8 that plunger:

The cainbar "il moved end- Wise by means ot a screw T8 which is threaded through a blocl) carried by the auger, has a swivel connection at one end with the cam bar 77 and .is provided 'at 'its other end with a hand Wheel SO. The cam bar 79 is held against rotation about its longitudinal axis by means ot a screwv 82 which engages longitudinal slot in the cam bar. lt will be seen that when the cani bai' is torce-.d in` Ward by rotation ot the 'Wheel 80, the plungers 30 are Yforced radially outward to break dovvn the coal, and hen the cainpbar is move,-L in the oppositey direction the plungers are retracted by the springs it.

rTheoperation of the machine `ivill be readily understood froin the foregoing description. Assuming, for the purpose ot illustration, that the machine is to be used in room and follows:

The coal having' been undercut by any desiree means, niy breaking down and loading` machine isset down adjacent the face ot the coal, preferably at one of the ribs. .ln Fig. l l have shown the machine disposed in the corner of kthe room :formed by the iace and the vright rib. The carriage C being: fully ret acted, the cable 68 is pased over the pulley Til and carried 'forward alonrjthe side ot the machine, as indicatedby dotted lines in Fig. l, and made fast at a point adjacent the 4lace. The movable shaft section T5 having been placed in position between the clutches 58 and 63, the motor is'noiv started so as to turn the Winding` drum 66 and draw the machine cndivise toward the tace of the coal. When the Tfront end ot the main trame A and the conveyer B have been projected fully into the bottom lrer't ot the coal, the motor is stopped., the shaft section removed, and the conveyer run into operative position and connected by means ot the clutch 58 with the shaft S ot thek conveyer i3.

The yoke which carries the auger D is then swung over to the lett by :utuating` the crank until it approaches a horizontal position, shown by dotted lines in lli. l.

pillar mine, the procedure 1s :rs

rlhis brings the auger about into the position lill) upivard against the overlyinnP coal or rock. JChe downward pressure oi' the plungers cases a portion ot the coal underlying' the to be broken doivn in the manner inin F of the drawing". The coal oocened 'tails upon the conveyer E t 'to the rear and discharges conveyer F which in turn dist into a mine rar. The coal haring been forced down7 the operator retracts 'the hf vlraulic plungers by opening the by-pass valve 42.

The carriage C is new retracted by turnf j the ren* 27 and the auger is then swung; over to the right to a position preferably somewhat above that shoivn in full lines in Fig. l and indicated by the circle o in Fig. 9. The clutch 12b is now thrown into operative position. the auger again ted forward. and the coal broken down and loaded 4into the car in the manner just described.

The carriage having` again been retracted, the pulley blocks 69 and T0 are made fast at suitable points to the left orp the machine, and the cable 68 is passed around the pulleys 69 and TO and thence baci: to the machine to which it made tast at 73. The Winding` drum 66 is now started by throwingr in the clutch G3. and the cable is thus Wound up until the machine is drawn rar enough to the lett to malte additional cuts v-ith the auger. .Preferably the machine will be mover far enough so that the auger, 1when svvunf.;r to an upright position, Will occupy the position indirated by the circle c in Fig. 9. vWith the aueer in this position.` the carriage is again red forward the operation of drilling'. breakingl dovvn and loading` is repeated as before. ln this manner the Work is continued until the machine been moved clear across the tace. During' the progress of the machine alone; the tace. the auxiliary conveyor F is gradually swung' about its pivotal support 4129, remaining constantly in operative relation with the main iart of the n'iachine and with the cars on the track.

`illhile l have shown a preferred form of my i1 .fentioin it should be understood that some of the parts can be mocitied Without affecting' the operation of other parts, and that some ot the features are useiul independently.
